LAN

Local Area Network LAN is usually abbreviated to a network computer network only covers a small area, such as campus computer networks, buildings, offices, in homes, schools or smaller. Currently, most LANs based on IEEE 802.3 Ethernet technologies using a switch device, which has a data transfer speed 10, 100, or 1000 Mbit / s. In addition to Ethernet technology, current technology, 802.11b (or commonly called Wi-Fi) is also often used to form the LAN. Places that provide LAN connectivity with Wi-Fi technology called hotspot.

On a LAN, each node or computer have their own computing power, different from the concept of a terminal dump. Each computer can also access resources on the LAN in accordance with the access rights that have been arranged. These resources can be data or devices such as printers. On the LAN, a user can also communicate with other users by using the appropriate application.

Unlike the Broad Area Network or Wide Area Network (WAN), the LAN has the following characteristics:

1. Having rapidly higher data
2. Geographically covering narrower
3. Does not require leased telecommunication lines from telecom operators

Usually one of the computers in the computer network that would use a server that manages all the systems within the network.
The characteristics of computer networks:
1. sharing hardware (hardware).
2. sharing software (software).
3. sharing of communication channels (internet).
4. sharing of data with ease.
5. facilitate communication between network users.
